Toxicity and Safety

Due to the fragility of ocular tissue, almost any eye contact with any ethylamine Both can cause irreparable damage, even blindness. Short-term exposure to ethylethylamine may cause severe skin burns, while prolonged exposure may result in harmful skin absorption of the substance. Exposure can cause an allergic skin reaction in some individuals. Ethylamine has low oral toxicity in a single dose. The dose of ethylethylamine for oral LD50 in rats is between 1000~4500mg/kg.

use the�The main hazards posed by ethylbenzamine (TEPA) are those associated with similar organic amines; namely the corrosive effects on the skin and eyes. Precautions should be taken to prevent contact with these parts of the body, such as the use of protective clothing and chemical goggles. If contact occurs, immediately flush exposed area with copious amounts of water for at least 15 minutes. Eye exposure should be checked by a physician. Contaminated clothing should be washed before reuse. If ingestion occurs, do not induce vomiting. Have individual drink plenty of water (or milk, if available) and get to a medical facility right away.

Processing and Storage

In order to maintain the high purity of tetraethylenepentamide (TEPA) production and transportation, The following storage and handling considerations are recommended:

Dry Inert Gas Pack

This product should be stored under a dry blanket of inert gas, such as nitrogen, to maximize Reduce pollution from contact with air and water.

Construction Materials

Storage tanks may be constructed of carbon steel if slight staining by ethylamine is acceptable or black iron, provided they are free from rust and wear. However, if the amine is stored in such tanks, color may develop due to iron contamination. If iron contamination cannot be tolerated, 304 or 316 stainless steel tanks should be used. (Note: Do not use copper, copper alloys, brass, or bronze in tanks or lines because they are quickly corroded by amines.) The recommended storage construction for TEPA is stainless steel or carbon steel.

Storage temperature

Tetraethylbenzamide (TEPA) has a pour point of -30°C. To avoid freezing, the product should be kept above this temperature.

Spills and Leaks

Small spills should be covered with inorganic absorbent and disposed of properly. Organic absorbents are known to ignite when contaminated with amines in closed containers. Certain cellulosic materials used for spill cleanup, such as wood chips or sawdust, have been shown to react with ethylamine and should be avoided. should be controlled and recycled. Water may be used for clean-up purposes, but release of material into sewers or natural bodies of water should be avoided. Disposal should comply with all federal, state and local laws, rules and regulations. Ethylamine leaks are usually identified by an odor (ammonia) or the formation of a white solid waxy substance (amine carbamate). Amine wastes can be removed using inorganic absorbents or water.

Packaging

Tetraethylpentamide (TEPA) is available in bulk and in 55 gallon drums, net weight 205 Kilogram.
